Tens of compounds used either alone or in combination ..... Because of major advances in biological and genetic research, the number of anticancer agents has increased in recent years. Overall, they are all designed to prevent the proliferation of cells that characterises cancers, or to destroy tumour cells. They also help the body to fight them.
The term "chemotherapy" is very often used in common language to describe the anticancer medicines. Etymologically, however, the word "chemotherapy" means any treatment based on a "chemical substance". At the start of the XXth century, the term was mostly used in infectious diseases. Nowadays, "chemotherapy" almost exclusively refers to oncology and means a medicine which attacks the DNA of tumour cells.
The different anticancer compounds
There are dozens of anticancer compounds administered either orally or intravenously. They can be grouped as follows:
- the "conventional" cytotoxic medicines;
- targeted therapy available for the last few years, are described as a revolution in anticancer treatments. Research is currently flourishing because of our improved understanding of the functioning of the cell and the receptors involved. At present, the main compounds used in these targeted therapies belong to the families of angiogenesis inhibitors (anti-VEGF) and signal transduction pathway inhibitors (anti-HER, anti-VEGF);
- immunotherapy treatments;
- hormone therapies.
